Normal human hearing ranges between 20Hz and 20000Hz. Sound waves having frequencies above the top audible range of human hearing are referred to as ultrasound. Beyond 20 kHz and up to many gigahertz, ultrasound equipment operates.
The initial examination of bat echolocation by physiologist Lazzaro Spallanzani in 1794 served as the inspiration for ultrasonic physics. Jacques Currie and Brothers Pierre make the discovery of piezoelectricity, which serves as the foundation for ultrasonic transducers, in 1877.
In the detection of submarines during World War I, ultrasonography is reported to have had its first practical use. Ultrasonic devices were first employed in a variety of industrial applications, including mixing, cleaning, and measuring distances and items.
The following types of ultrasound equipment used in hospitals are frequently observed:
• Sterilization & Cleaning
• Therapeutic
• Diagnostic
When doing ultrasonography, high-frequency sound waves are utilized to produce pictures of anatomical structures. These images are then evaluated by medical professionals to check for anomalies.
With the use of this technology, it is possible to identify a variety of chronic disorders that affect vital body components including the heart, joints, and abdominal arteries. Additionally, it is among the safest non-invasive methods for organ inspection.
What distinguishes an ultrasound from a CT scan?
Another frequent medical imaging method used to detect diseases inside the body is a Computerized Tomography (CT) scan. But this is very different from how an ultrasound scan is done.
X-rays are used in CT scans to produce an in-depth view of the body's interior organs. To take pictures of various bodily tissues and sections, the X-ray tube rotates.
Surging Cases of Chronic Illnesses Demand for Ultrasound Devices Is Growing
Due to changes in lifestyle and a lack of accessibility to preventative treatment, the incidence of chronic diseases such as diabetes, cancer, heart disease, and respiratory illnesses is rising.
For example, over 18.1 million cancer incidences were identified and almost 10 million fatalities, or about one in six deaths, were reported globally in 2020. The demand for cost-efficient, therapeutic ultrasound techniques, and minimally invasive diagnostics would rise as the prevalence of these disorders increased.
